AzerothCore is a core based upon SunwellCore which is based upon TrinityCore.I'll quickly talk about why custom server developers should use it, especially people with new gameplay ideas as it's often the case on modcraft.Sorry if it's not well structured or if it's lacking information.

Advantages over TrinityCore

Better for playersIt has been mainly worked on by private server developers unlike TrinityCore (many devs there aren't interested by making playable private servers at all). Almost everybody who contributed to AzerothCore runs his own small public server at the moment, so they want as few bugs as possible for their players.The two developers behind SunwellCore had a server with 3000 players online in January 2016 when they released their code and shut down their server.The two founders of AzerothCore also worked on their own small private (but public) server.

It translates into a more polished experience for players, less bugs (look at the SunwellCore features), less complaints and a top notch stability. The database is included in the repo (with working dungeons and raids for example).

Custom modulesThe core makes use of custom modules which allows us to plug them in and out easily, and which doesn't require us to modify the core files. It also means we can keep pulling the git changes from the main repository if we only work with modules.

Extras featuresA better configuration file system which allows us to use a tiny configuration file for better readability and maintenance.A (very) new feature allowing people to disable some unneeded features to increase the performances.A script to easily merge all new SQL updates into one without worrying much.Several custom modules available (such as a Transmogrification module).Based on TrinityCore, so many things are compatible with AzerothCore or require minimum modifications.Sunwell team provided custom addons (raid browser and arena spectator) to use as well which should work very well on AzerothCore.For now, there is no need to extract the client data, it's available as a direct download.

thanks alot i loved TC when they where good and you could do stuff on it. i will give this a shot maybe a server for me. yea sadly it dont can use Eluna but i guess it will get supported maybe. depening on if this core takes of
